Ilias Kasidiaris, 32, faces charges of attempted grievous bodily harm over last June's incident, in which he repeatedly slapped one woman and threw a glass of water at another before running away. The attack followed an exchange of verbal abuse.

Kasidiaris is the spokesman for Golden Dawn, a far-right anti-immigrant party that rose from the margins of politics to win 18 of parliament's 300 seats later last June.

The party rejects the neo-Nazi label but is fond of Nazi literature and references.

Lawmakers voted 205-3 on Wednesday to strip Kasidiaris of the immunity from prosecution enjoyed by all Greek parliamentarians. No trial date has been set.
